The Javalambre Photometric Local Universe Survey (aka J-PLUS) has covered almost 500 square degrees since it started operations in November 2015. J-PLUS is conducted by the 80-cm diameter Javalambre Auxiliary Survey Telescope (JAST/T80), which, despite its modest size, has a relatively large Field of View (~2 square degrees). The camera attached to JAST/T80 counts with a system of five broad band filters (u_JAVA, g_SDSS, r_SDSS, i_SDSS, z_SDSS) plus seven narrow band filters (of width ranging from 10 to 20 nm). Four of these narrow band filters are centered upon Halpha, Hdelta, Ca Triplet, and OII 3727A (rest frame).  After a strategic redefinition of  filter depths, JAST/T80 should cover the Javalambre sky at a speed of 1500 square degrees per year. I will briefly describe the instrument and the survey specifications, together with some of the scientific projects under development, and their preliminary results. I will also describe the J-PLUS online data base in an attempt to encourage members and potential members of the collaboration to exploit these data.

ALMA is a submillimetre/millimetre telescope located at 5000m in the Atacama desert in Chile designed to observe at 0.32–9.5 mm (31–950 GHz), and it is expected to be the leading observatory in these wavelengths for many decades to come. ALMA has performed scientific observations since September 2011, with new capabilities being offered for each new observing cycle. The interface between ALMA and the astronomical community is provided by the ALMA Regional Centres (ARCs). The European ARC is located at ESO, Garching. In Europe, the services to the community are provided by a distributed network of ARC nodes. The European ARC network is an international, geographically dispersed structure, and consists of the central ARC at ESO, seven ARC nodes and one Centre of Expertise, distributed across Europe. It is an organised effort to provide the European ALMA user community with uniform expert support from the stage of proposal preparation through to data reduction, in order to enable the optimal usage and increase the scientific output of ALMA. The model for the European ARC nodes network will be described in terms of its organisation, communication strategies and user support. ALMA capabilities and recent ALMA results will also be summarised.
Depending on the interest of the participants, the talk can be followed by a small demo of the ALMA Observing Tool (OT) for the creation and submission of ALMA proposals, as well as the ALMA Snooping Project Interface (SnooPI), that allows PIs and Co-Is to follow their projects throughout their life-cycle.

The IAC is part of the  Southeastern Association for Research in Astronomy (SARA), a consortium of colleges and universities in the US partnered with Lowell Observatory, the Chilean National Telescope Allocation Committee, and the Instituto de Astrofisica de Canarias.

In this seminar I will describe the remote facilities operated by the SARA observatories that comprise a 0.96m telescope at Kitt Peak, Arizona; a 0.6m instrument on Cerro Tololo, Chile; and the 1m Jacobus Kapteyn Telescope at the ORM. All are operated using standard VNC or Radmin protocols communicating with on-site PCs. Remote operation offers considerable flexibility in scheduling, allowing long-term observational cadences difficult to achieve with classical observing at remote facilities. Multiple observers at different locations can share a telescope for training, educational use, or collaborative research programs. Each telescope has a CCD system for optical imaging, using thermoelectric cooling to avoid the need for frequent local service, and a second CCD for offset guiding. SARA Kitt Peak telescope also has a fiber-fed echelle spectrograph. Switching between imaging and spectroscopy is very rapid, so a night can easily accommodate mixed observing modes.

The IAC astronomers started to use SARA facilities since early 2016 and a new call for proposals is open. I will present some early results from IAC’s observational programs and discuss the present status of the facilities and the experience obtained by the IAC users that could help new potential observers to prepare their own proposals.

An exciting series of changes are taking place at the venerable WHT and INT on La Palma. WEAVE, the next generation multi-fibre spectrograph is being completed for the WHT prime focus. Once built, it will carry out massive surveys of stars, the Milky Way, galaxy evolution and cosmology. At the INT, the HARPS3 high-resolution stabilized spectrograph is being built. It will provide the ING communities with a world-class exoplanet research tool. This talk will address the observing opportunities brought by these two instruments, their development calendars, and ING’s plans to retain additional instrumentation for the open time. I will describe how the telescopes will be operated, both in the survey time and the open, TAC time.

In coincidence with the announcement of the call for proposal of the Spanish night CAT for semester 2017A, we present the new web page OOCC. This is the new astronomer portal of the IAC, and it targets the Spanish community with all the necessary information to access and observe with any telescope at both Observatorios Astronomicos de Canarias, that is the Observatorio del Teide and the Observatorio del Roque de los Muchachos. The new portal, developed by the IAC Telescope Operation Group in agreement with the Presidents of both the night and the solar CATs, supersedes the old and pages. In this talk we will present the most important aspects and possibilities of the portal.

I will summarize the two well proved techniques for high spatial resolution: Lucky Imaging and Adaptive Optics and the work of our group in this field. I will also introduce the state-of-the-art new instrument Adaptive Optics Lucky Imager (AOLI). On AOLI, both techniques merge providing a very versatile answer on the visible range. Some first science on the T-Tauri system LkHa 262/263 in the MBM 12 cloud will be reported together with a review of the next steps to be developed.

The Square Kilometre Array (SKA) project intends to build a radio-interferometer with 1-sq-km collecting area, and thousands of antennas with baselines up to 3000 km, to be hosted in two continents (Africa and Oceania). This will provide tens of times more sensitivity and allow astronomers to survey the entire sky thousands of times faster than any system currently in existence, with the ability to image huge areas of sky in parallel.

Spain is actively participating in the SKA detailed design phase, both at a scientific and technological level. The potential of SKA for fundamental breakthroughs in Astrophysics, Physics, and Astrobiology has made that the Spanish SKA White Book has been published, with more than 125 authors who have summarized in 29 chapters the interest of the Spanish scientific community. At the same time, SKA constitutes a technology tractor for high-impact societal areas. Among the 100 companies and research institutions across 20 countries that are contributing to SKA design, 10 Spanish research centres and 11 companies participate in several work packages (Dishes, Signal & Data Transport, Central Signal Processor, Science Data Processor, Telescope Manager, and Infrastructure). This Spanish technological participation in the SKA, with an estimated financial value of ~€2M, has been officially acknowledged by the SKA Board. Since October 2013 a representative of the Spanish government has been regularly invited to participate in the SKA Board meetings. Furthermore, at the beginning of 2014, the Board of the Spanish Astronomy Infrastructures Network endorsed the recommendation issued by the Radio Astronomy Infrastructures working group on the interest of the scientific community and industry that Spain explores the possibility to join the SKA project as Full Memb er before the construction phase starts. The interest of the Spanish community and industry was restated during the SKA Spanish day held in October 2014 while a new SKA Spanish Industry Day will be organized by CDTI in 2016.

The aim of this talk is providing a retrospective view of the Spanish participation in SKA project and explain the current status of its participation and opportunities of involvement.

In collaboration with member states institutes, the use of the synergies with ESO is producing first important results in the R&D for Laser Guide Star adaptive optics, to be used for the large and extremely large telescope projects.

In this talk we will report on the preliminary results of the current campaign on LGS return flux with laser guide stars at Observatorio de el Teide and the foreseen tests of the EELT LGS-AO scheme, to be done at the WHT starting in summer 2016. An outlook will be given on the proposal for further feasibility tests at WHT in 2018-19, to experiment novel LGS-AO schemes using uplink beam correction and pyramid wavefront sensing. The demonstration is for a LGS-AO scheme giving high Strehl on the EELT and adaptive optics in the visible on 8m class telescopes.

The Observatorio Astrofísico de Javalambre (hereafter OAJ) is a new Spanish astronomical facility devoted to carry out large sky multi-filter surveys with two telescopes of large field-of-view (FoV): the Javalambre Survey Telescope (JST), a 2.5m with 3deg FoV, and the Javalambre Auxiliary Survey Telescope (JAST), an 80cm with 2deg FoV. Both telescopes are equipped with panoramic cameras that amount to 1.3Gpix and are able to host more than 80 different filters simultaneously. During the first years of operation, the OAJ will be mostly devoted to conduct the Javalambre Physics of the Accelerating Universe Astrophysical Survey (J-PAS) and the Javalambre Photometric Local Universe Survey (J-PLUS). J-PAS will observe 8.500deg2 of the sky visible from Javalambre with a set of 54 narrow-band contiguous optical filters plus 5 broader ones, performing in the end as a low resolution IFU of the Northern hemisphere. It will provide unprecedented spectral energy distributions for every pixel of the sky, and ultimately for more than 200 million galaxies. J-PLUS is now beginning to observe the same sky area of J-PAS with 12 narrow, intermediate and broad-band filters aimed to provide the photometric calibration of J-PAS and unprecedented multicolor data for many fields of the Astrophysics. Both J-PAS and J-PLUS will provide powerful 3D views of the Universe that will be made publicly available to the community as legacy projects. In this talk I will present the OAJ and the J-PAS and J-PLUS projects, describing the survey strategies and their main scientific objectives and capabilities.
